Solar cell substrate having a first conductivity type; Located on one side of the substrate, the first direction a plurality of first electrodes extending in; Is connected to the plurality of the first electrode, the emitter having a first conductivity type opposite the second conductivity type taboo; Located on the other surface of the substrate, the first direction a plurality of second electrodes extending in; And a local location to a plurality of the position corresponding to the second electrode, including a plurality of second electrodes are formed in the same direction as the plurality of the back of the field unit which includes a plurality of first field portion electrically connected to the second electrode, and , the distance between the first direction and perpendicular to the first system unit I claim along the second direction adjacent to each other are formed narrower than the interval between the second electrode are adjacent to each other in a second direction.
